71023141 - Arcair N7500 Automated Gouging System with Bug-O Tractor

Precision Automated Metal Removal System

The Arcair N7500 Gouging System (SKU: 71023141) represents the pinnacle of automated air carbon arc gouging (CAC-A) technology, designed specifically for heavy industrial applications where consistency, speed, and depth control are paramount. This specific configuration is engineered as a turnkey solution, integrating the robust N7500 control architecture with a high-performance Bug-O travel carriage (tractor) operating on 220 VAC. This combination allows fabrication shops and shipyards to automate long-seam back-gouging and joint preparation tasks with exceptional precision.

At the core of the system is the N7500 controller, which utilizes advanced digital feedback loops to monitor arc voltage and automatically adjust the electrode feed rate. This ensures a constant arc length is maintained throughout the gouging process, regardless of minor variations in the workpiece surface. The system is capable of handling a wide range of jointed carbon electrodes, typically from 5/16-inch up to 3/4-inch diameter, making it versatile enough for both medium and heavy-duty material removal rates. The inclusion of the Bug-O tractor transforms the unit into a track-mounted powerhouse; the tractor provides steady, regulated travel speed along the workpiece, which is critical for achieving uniform groove geometry that manual operation simply cannot match.

Technically, the system requires a suitable high-amperage DC welding power source (CC or CV modes supported) and a compressed air supply. The 220 VAC requirement for the Bug-O tractor ensures compatibility with standard industrial auxiliary power lines. The package includes the gouging head, the remote pendant for operator adjustments, the control box, the tractor unit, and necessary interconnecting cables. By mechanizing the gouging process, the N7500 system not only improves the metallurgical quality of the prepared joint by minimizing heat input variations but also significantly increases throughput by allowing for continuous operation with jointed electrodes.
